Overview

Milky Spore targets and kills Japanese beetle grubs, a familiar destructive pest, before they can grow into adult beetles. At the immature stage, Japanese beetle grubs feed on the roots of lawns, turf, and other grassy areas. The adult beetle feeds on flowers, ornamental plants, trees, shrubs, and the foliage of some field crops.

Originally developed by the USDA, Milky Spore is a naturally occurring bacteria Bacillus popillae host-specific to Japanese beetles. In areas treated by Milky Spore, Japanese beetle grub eat the spores during their normal feeding patterns. Then the spores reproduce inside the grub, eventually killing grub within 7-21 days. As the grub decomposes, it releases millions of new spores and these multiply and kill other grubs.

Milky Spore is safe for people, pets, wildlife, beneficial insects, and soil microorganisms. It does not affect streams, ponds, or groundwater. Product is approved and registered with the US Environmental Protection Agency.

Features & Benefits:

  • 40 oz. Box can treat up to 10,000 square feet
  • Targets Japanese Beetle grubs feeding on roots
  • Naturally occuring bacteria Bacillus popillae
  • Kills grubs within 7-21 days while releasing even more spores
  • Developped by the USDA and approved by the US Environmental Protection Agency
  • Safe for people, pets wildlife and waterbodies

Application:

Coverage: 40 oz. box treats 10,000 square feet.

Apply one teaspoon of Milky Spore powder to turf every 4 feet in rows 4 feet apart. It should look like a grid pattern when finished. Areas between direct applications will be inoculated naturally. Best results can be expected once the entire area is inoculated. Milky Spore requires only one application, lasting ten years or more.

It is most effective to apply Milky Spore in the summer and early fall. The soil must be above 65 degrees F when the grubs are actively feeding, which is the best time for application. It works best to apply just before rainfall, or water in lightly after application to soak into soil.

To apply Milky Spore, you can make a homemade dispenser by punching 15 nail holes into a 1 lb. coffee can, and attaching with duct tape to a 4 foot stick six inches from the bottom.

    Milky spore and tube dispenser

    Prefer the granular put down with a spreader. The cardboard tube clogged up with the powder. I had to loosen the powder, quite frequently to get it to dispense the right amount of powder. I put it on when the grass was dry. The powder seemed to compact at the end of the tube reducing the amount dispensed.

    Easy to use

    I'm not sure of the results of the use of the powder. I hope we see fewer japanese beetles in the spring. I'm glad I found this as an option and it's very easy to use. thanks!
